Kousuke | Ooshiba

Kousuke’s narrative utility is built upon the subversion of his "bad boy" reputation. While his past is marked by physical prowess and a confrontational nature—illustrated by his willingness to confront neighborhood thugs—this aggression is consistently directed toward protection rather than exploitation. This duality defines his role as a "hero" in Masahiro's eyes. However, the series complicates this dynamic by transitioning Kousuke from a distant savior into a high school math teacher, creating a power imbalance that forces both characters to navigate the ethical and emotional boundaries of their evolving relationship.
